low boost from oil leak?

I have a 99 psd 7.3l with 260k miles, "built" turbo w/wicked wheel, cone filter and an overkill 10" exhaust stack. Supposedly swamps injectors and new glow plugs. Truck is hard to start and blows white smoke before starting when its cold out...but glow plug relay will be replaced tonight, hopefully clear that up. Runs like crap when cold, as soon as it hits the mark above the "c" instantly smoothes out.

Problem im most concerned with is an oil leak and low boost. ebpv deleted completely, non ebpv pedestal, so its not that. I have an oil puddle under the pedestal, and if the light hits it right, you can see the reflection on the firewall of the puddle making waves from oil dripping every 5 seconds or so (engine off).

I also have low boost..max 11psi on mechanical gauge tapped into y pipe (has boost fooler on map since the turbo is supposedly "built". I disconnected the wastegate line and plugged it and it will max at about 18 psi that way. Checked all the boots and tubes and all look good. has a full aluminum intercooler so I don't think its cracked like the plastic ones suffer from.

recently changed the ipr, oil, and fuel filter. engine also ticks much louder than other powerstrokes especially after a heavy foot, sounds like its under the truck..fairly new (10000 miles ?) auto trans from ford btw

drivers side up pipe looks clean, can't get a view of the passenger side at all...wondering if a pedestal oil leak would also cause a boost leak. don't really want to pull the turbo, but I will if I have to
